I am working on Magento Data Migration from 1.9 to 2.2. I customised some code and suppressed some of the possible errors of integrity constraints to execute the tool properly and get the data.
However, I can see some of the rows in catalog_product_entity_varchar are not fully migrated. In the same process of comparing no of rows, I found that some of the tables from source (1.9) database which are starting from m2_cl_ etc.
What are those tables? They all are blank? but Does they have any relations with missing rows and non-migrated data?
